On a more positive note, ultra cleaner has brought the hard rubber items up like new, although residue from salt solution is still on them.

Even a carb air hose found on a spare engine, only one small split found on this one.

Used my home made shocker dismantling tool on one Honda rear shocker, has only been used on Bantam ones so far and it fell a bit short, but a bit of help from hydro press got both studs engaged and compressing commenced.

Couldn't see what I was doing very well and ended up putting a tiny crack in bearing, it's worn as well, but I feel I may have put the rebuild back a long way now.  

Set of new headraces isn`t going to set you back price & timewise is it, surely? Doesn`t matter that you cracked it, looking at the wear/indents it was cream-crackered anyway.

Is David Silver any good for spares?

Hello Blue, no, I simply thought new Honda yoke bearings for this bike would be all used up by now? Not unless there's some stashed away somewhere, or even someone re-making them?

I'll make some enquiries, thanks for commenting. DD.

Can you knock a set up on the lathe?

What's 7/16 in mm again?

Hi,

In preparation for my 1968 CB 250 Super Sport I got some NOS stuff, including two pistons from Thailand! So stuff is about.

Dave Silver also has a load of stuff.

D7/14 hybrid (4 speed with D7 crank etc.) on the road, D10 Bushman awaiting rebuilding.

Thanks for posting but I very much doubt it, I imagine they're cast steel of high quality, you'd have to make new ones to a very high standard and finish off by grinding, they'd then need heat treating etc. new ones are cheap in comparison to trying to turn a shed into a dedicated bearing production facility.

Cheers Cocorico, I've ordered a few new parts from David Silver, but saw no yoke bearings on parts list for my bike, I'll give them and ring to be sure though.

Sometimes Japanese parts fare less well than our own indigenous ones.

As well as blistered rust, it was leaking too, at seal on output shaft.

Just scrap now.

Went to Litchfield last Saturday to pick up more parts, essential items nearly all, were picked up with relief ay not having to locate everything new. Only one good silencer out of the two.

** Please log in to view **

A good set of proper CD bars, a spare headlamp cowl, even a set of cafe or race type bars, which I hope to sell on if anyone's interested.

A good igniton switch with key and working was appreciated.

Not sure how the British prefocus reflector got in there, but I'm not complaining about it, will go on another Bantam or Cub, no doubt.

** Please log in to view **

Main items were a pair of mudguards, a bit better than mine, lots of work needed though.

I found that a CG125 tank mounting rubber set was almosdt identical to the CD ones.

** Please log in to view **

Chain guard top end I took off bike is wrong, but this one appears correct, only time will tell, as CD set up is fairly complicated with so many parts on the fully enclosed variety.

** Please log in to view **

I made a bit of a gaff when I took a set 'B175 Bantam' gaiters to see if they could be persuaded to fit the CD, a PO had cut one in half and affixed it via cable ties, furthering the lie that it was correct.

I've made inroads into making my own replacement steel covering tubes, since.

After 'tin openering' one of the chromed lower leg covers off, I was able to get to single internal circlip that holds everything in on one scruffy fork leg.

Only built a year after the last Bantam was, it's amazing how the Japanese responded with such good, efficient and well chromed stuff like this, BSA certainly had things to learn yet it seems. No signs of rust or corrosion and only a little wear detected.

** Please log in to view **

Amazingly, partly perished and only seal is still a nice sliding fit on stanchion and still not letting oil past.

 

A P.O. had somehow almost missed the snapped off bolt with their drill bit, it took only a few minutes with pillar drill and tap to get it back to normal, which taught me that trying to fix seized up bolts without removing leg is a big mistake.

Had to be content with cleaning up odd items I won't really need for a long time, wanted to be sand blasting really, but it's a major upheavel involving putting ,many bikes outside etc. in this present weather that'd be a mistake.

Have you tried CMS in Holland ? they seem to have lots of stuff for most japanese bikes, plus excellent schematics,

Thanks Bart, just ordered a pair of bearing cups from them, their ball bearings @ 50 pence each were a bit dear though. 18 quid for 36 if I'd gone with them and folk think Bantam stuff is dear?.

22 quid for two cups and nearly another 22 for postage and vat, (incl. vat on postage!)  I wonder if vat will be finished if we leave the EU? I doubt it.

But I need the parts to be able to get on, so I must endure.

Not much cop to you now Mags, as you`re sorted, but if you do another CD etc, then there`s these...** Please log in to view **

Just remembered, one of my T20s has tapered head bearings fitted.....and my Bantam Cub came with a Honda 125 front-end with extended head-stock for Honda stem, but not stripped that to see if it`s got tapered bearings or ball set up, yet.

Some wshing up liquid, a clean cloth and some hot water were got together to see if I could improve the Wrexham bought seat.

** Please log in to view **

Went over it six times with the whitish rag coming up black and brown.

Salt residue from the wash up liquid is only drawback.

Even dirty water can still clean, if warm, even better.

** Please log in to view **

Tank rubbers wewre thrown in for good measure.

** Please log in to view **

Seat looked much better when dry, but, there's powdery rust on other side, which I intend to remove via a rotary wire brush, rust killer and a decent coat or three of new paint.

A free and roughly eight foot length of stainless tubing, was refused by a welder friend of mine a year or two ago, so it sat here, until a few days ago.

** Please log in to view **

I measured the place on lower fork leg where the chromed pieces of tube, about four or more inches long, sat.

** Please log in to view **

Did the same on the stainless and got this, but I found tubing has been knocked about a bit and isn't actually still round where I measured it. One end was black, as if it'd been in a fire!

Not very encouraging, I admit.
